i think kishimoto's the creator.
& why am i reading people say madara's chakra is more sinister, what i read in both the manga & the anime was that hs blood is more sinister.

its about time he kills orochimaru

if oro dies now, then there's no point in the continuation of the sasuke retrieval mission, from whom will naruto rescue sasuke anymore ?.. . from no one to save.. . obviously if oro will be killed sasuke will be able to do anything, and i am sure that sasuke will not go back to village, but now, naruto will not have the reason to rescue sasuke now.. . coz now its own sasuke's decision . i mean, he now not being held captive .. ..

killing oro of now, just mean a loss of another ARC, and a great one .. . . a probable rematch bet. oro and jiraiya. . .. a fall of another story to tell. . . so yeah .. .killing oro of now is not is not the next best thing. .. .
